The security1 of embedded systems has received much attention due to its widespread use and open application environment. Hash function is a commonly used solution to protect embedded system security. Due to the influence of area and power consumption, traditional hash encryption algorithms cannot be directly applied to embedded system because they consume too many resources. Therefore, lightweight encryption algorithms are receiving more and more attention. This paper proposes a method of applying LHash in embedded systems. The experimental results show that the method can correctly implement the LHash algorithm, and can simultaneously consider the area, power consumption and encryption speed, and has good applicability and security.
